Currently, nouveau doesn't actually bother to try probing whether or not it can actually handle interlaced modes over DisplayPort. As a result, on volta and later we'll end up trying to set an interlaced mode even when it's not supported and cause the front end for the display engine to hang. So, let's teach nouveau to reject interlaced modes on hardware that can't actually

This patch series adds TV-out modesetting support to the KMS implementation. I've tried to test it on all the hardware I've got at hand (that is nv11, nv17, nv34, nv35, nv40, nv4b) with every possible output combination; I believe it has reached a mergeable state, however it depends on some commits from drm-next that haven't got into Linus' tree yet, if you agree to merge this

This is mainly for dropping interlaced modes on DP connectors if the GPU would otherwise display garbage or EVO timesout. It also adds experimental detection of the HDMI clock limit we currently hard limit depending on the GPU generation. Starting with GF110 GPUs, we can retrieve the limit directly from the GPU and may make the hdmimhz parameter obsolete. Testing this series with 2560x1440 or

small update to my last version I sent out. Patches 3-6 are optional and should only improve detecting the max clocks for HDMI and DP, but they didn't underwent big testing and I am a bit concerned, that it might break detecting the DP limits on some boards.

It seems it was only locking up in the context of nouveau_hw_save_vga_fonts, when it actually did something (because the console wasn't already in graphics mode).

Most of the reason I'm asking for an RFC here is because this code pulls a lot of code out of i915 and into shared DP helpers. Anyway-nouveau's HPD related code has been collecting dust for a while. Other then the occasional runtime PM related and MST related fixes, we're missing a lot of nice things that have been added to DRM since this was originally written. Additionally, the code

To start off: this patch series is less work to review then it looks - most (but not all) of the nouveau related work has already been reviewed elsewhere.
